| PST-SQ400B Product FAQ | |
| Q1: What is this product? A: This is a WiFi Smart Water Leakage Detector by Tuya. It's designed to detect water leakage and alert you in case of any unwanted water presence. |
|
| Q2: Which WiFi frequencies does it support? A: It supports 2.4G Hz b/g/n WiFi frequencies. |
|
| Q3: How do I connect the sensor to my Wi - Fi network? A: Download the Tuya Smart app from the app store. Open the app, create an account if you don't have one. Then, follow the in - app instructions to add a new device. Select the Wi - Fi vibration sensor and enter your Wi - Fi password when prompted. |
|
| Q4: What if my Wi - Fi signal is weak near the sensor's location? A: You may consider using a Wi - Fi extender or a mesh Wi - Fi system to boost the signal. Ensure that the sensor is within a reasonable range of your router for optimal connectivity. |
|
| Q5: Is it a standalone device? A: Yes, it's a standalone device. However, it requires a WiFi connection and can be managed through the Tuya app for full functionality. |
|
| Q6: Where should I install this water leakage detector? A: It should be installed in areas prone to water leakage, such as near water heaters, sinks, washing machines, dishwashers, and in basements or crawl spaces. |
|
| Q7: How is the sensor powered? A: The sensor is powered by DC3V CR123A Lithium battery. |
|
| Q9: How long does the battery last? A: Battery life depends on usage frequency and sensitivity settings. Under normal usage and default settings, the battery can last approximately 12 months if trigger 10 times a day. |
|
| Q10: What should I do if the sensor doesn't connect to my Wi-Fi network? 1. Check the Basics Power: Ensure the sensor is properly powered. Wi - Fi Signal: Make sure the sensor is within range of your Wi - Fi router. 2. Reset the Sensor 3. Re - add the Device in the App 4. Check Router Settings 5. Update Router and App Firmware |
|
| Q11: How does the water leakage detection work? A: The detector uses sensors at its probe end. When water comes into contact with the probe, it triggers a change in electrical conductivity, which the device then detects and interprets as a water leakage event. |
|
| Q12: Does the sensor work with voice assistants? A: It supports Amazon Alexa and Google Assistant. |
|
| Q13. How sensitive is the detector? A: It's highly sensitive and can detect even a small amount of water on the probe to quickly alert you of potential leakage. |
|
| Q14. Which app should I use to control this device? A: You can use the Tuya - supported app. You can download it from the App Store (for iOS) or Google Play (for Android). |
|
| Q15. Can I control the device remotely? A: Yes, as long as the device is connected to WiFi and your phone has an internet connection, you can control it remotely through the app. |
|
| Q16. Can it distinguish between different types of liquids? A: It's primarily designed to detect water. While it may react to other conductive liquids, its main function is focused on water leakage detection. |
|
| Q17. The sensor is constantly sending false alerts. How can I fix this? Lower the sensitivity level in the app. Also, check if there are any sources of constant vibrations near the sensor (e.g., appliances) and relocate it if needed. |
|
| Q18. The app can't find the sensor. What's wrong? Ensure the sensor is powered on and in pairing mode. Also, check your phone's Bluetooth and Wi - Fi settings, and make sure they are turned on. |
|
| Q19. Can someone else access my sensor's data? As long as you keep your app account credentials secure, and your Wi - Fi network is protected, it's very unlikely that others can access your sensor's data. |
|
| Q20. How quickly does it detect water leakage? A: It has a fast - response time and can detect water leakage within seconds of the probe coming into contact with water. |
|
| Q21. Does it work in low - light or dark environments? A: Yes, its water - detecting function is not affected by lighting conditions. It focuses on detecting the presence of water rather than relying on light. |
|
| Q22: How will I be alerted when water leakage is detected? A: You'll receive a push notification on your phone through the Tuya app. Additionally, the detector may have an internal buzzer that sounds an alarm (if enabled in the settings). |
|
| Q23. Can make OEM? A: Yes, we can. PID OEM:500PCS Box & manual OEM: 1000PCS, if only 500PCS extra charge 0.20USD/PCS; Laser Logo: 100PCS |
